Abstract

In this study, the vibration analysis for the existing arch bridge induced by a motion exciter is conducted in order to understand the vibration characteristics which could reflect structural soundness of the existing arch bridge, such as natural frequencies and response power spectrum. Based on these analytical results, Self-Organizing feature Map (SOM) is applied to evaluate the structural soundness and its applicability is discussed. It is analytically concluded that the proposed evaluation method has the potential to classify the damage of members in an existing bridge structures.
